Alyssa Milano is rallying women to take a stand against sexual harassment and assault with two simple words: ‘Me too’.

The American actress, the latest celebrity to speak up about sexual violence in the wake of the Harvey Weinstein scandal, posted on Twitter on Sunday, asking other women to come forward to reveal the 'magnitude of the problem'.

She tweeted a note, which read: “Suggested by a friend: If all the women who have been sexually harassed or assaulted wrote ‘Me too’ as a status, we might give people a sense of the magnitude of the problem.”

“If you’ve been sexually harassed or assaulted write ‘me too’ as a reply to this tweet,” she captioned the image.

The tweet received more than 23,000 comments with many women, including some famous, writing ‘me too’ and even sharing details about their experiences.

Twitter has been flooded with the hashtag #metoo by women indicating they have been the victim of sexual violence or harassment.

In a blog post published last week, Milano said she had purposefully steered away from directly commenting on the Weinstein scandal due to her close relationship with his now estranged wife, Georgina Chapman, who she worked with on Project Runway All Stars.

"Georgina Chapman is my friend. She is one of the most special humans I have ever met. Harvey and Georgina also have two very young children who my children have known their entire lives,”she wrote.

“It is because of my love for Georgina, India and Dashiell that I haven't publicly commented on this until now. Please don't confuse my silence for anything other than respect for a dear friend and her beautiful children."
